Update build_update_taxon_list.R

• Add dplyr:: prefix to filter functions to avoid conflicts with stats::filter
• Clean formatting

This is before I import it to traits.build

looks good - but curious how many of the reformatting were automated by R vs intentional? (To avoid this happening in reverse when I next edit it with different RStudio settings, since it makes it hard to see the actual changes.)

@ehwenk The removal of trailing whitespaces is an automated shortcut I have on VS Code any time I save a file (it's not to do with R settings). Everything else was intentional reformatting.
